HM-WF8266A 2.4GHz WIFI Wireless Transceiver Module Specification HM-WF8266A E-mail:sales@hoperf.com www.hoperf.com Rev1.
HM-WF8266A 1. Product overview HM-WF8266WiFi module, developed by HOPERF Microelectronics Co., Ltd., provides a highly integrated Wi-Fi SoC solution with low power consumption, compact design and high stability to meet the needs of users. HM-WF8266WiFi module has a complete and self-contained Wi-Fi network function, which can be used independently and run as a slave plane mounted on other host MCUs. When HM-WF8266 is used independently, it can be booted directly from external flash.

HM-WF8266A 8. Power Management Unless otherwise stated, the following power consumption data is tested with a supply voltage of 3.3V and an ambient temperature of 25° C; the Tx power consumption data is based on a 50% transmit duty cycle. Notes: ① Modem-sleep mode is used in the applications that require the CPU to be working, as in PWM orI2S applications. According to 802.
HM-WF8266A FCC NOTICE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
HM-WF8266A The equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. The equipment should be installed and operated with minimum distance 20cm between the radiator & your body. If the FCC/IC identification number is not visible when the module is installed inside the host, then the outside of the device into which the module is installed must also display a label referring to the enclosed module.
